Fig. 7From: Comparison of whole blood cytokine immunoassays for rapid, functional immune phenotyping in critically ill patients with sepsisTNF production, over time, in response to LPS stimulation of whole blood from critically ill survivors versus non-survivors. A Log2-transformed TNF concentration as measured by ELISpot immunoassay, B log2-transformed TNF concentration as measured by ELLA immunoassay. Top panels illustrate cytokine production per microliter of blood, and corresponding bottom panels illustrate cytokine production per 103 monocytes. Day 1 denotes the day of study enrollment; dots represent mean values ± SEM. P values denote significant differences between stimulated TNF production in whole blood of survivors versus non-survivors, based on linear mixed-effects analysis. At day 1, n = 24 survivors, 8 non-survivors (7 critically ill and septic and 1 critically ill and non-septic)Back to article page
